So after doing this diet for 5 weeks I still am a bit confused! Anyway basically what I do is have 4 200cal products a day (normally Cambridge but have swapped one of them for Slimfast occasionally) and probably around 50 cals of milk. The milk is not strictly part of step 1b but my counsellor is happy for me to have it. I have lost 27lbs in 5 weeks as of this morning. Kind of wanted my 2 stone off then I would been in the 13s but that is probably slightly unrealistic!
The first week I found hard, not going to lie. I was really tired and couldn't do much at all. Strangely I wasn't very hungry. I genuinely haven't been very hungry for proper food, despite buying and cooking it for my daughter. Sometimes tempted but nothing really bad. I just drink a couple of glasses of water and I'm OK.
It's great that you have planned your food, that will definitely help you avoid temptation when you are hungry if you know what you're going to have. What I love about this diet as well is the fast results, they have definitely kept me motivated. If you keep to the plan you pretty much guarantee to lose weight. But with WW or SW it wasn't that straightforward when I did it.
